On the surface, a first movable block 23 is rotatably connected to the surface of the base 2, a first spring 24 is fixedly connected to the surface of the first movable block 23, a second movable block 25 is fixedly connected to the surface of the first spring 24, the second movable block 25 is rotatably connected to the surface of the seat body 1, and a buffer pad 26 is fixedly connected to the surface of the seat body 1. The buffer mechanism slides on the base 2 through the seat body 1, and the cooperation of the telescopic damper 22, the first spring 24 and the buffer pad 26 effectively reduces the impact force of the seat body 1 on the child, thereby improving the safety and comfort of the child safety seat.

[0025] Furthermore, an anti-collision mechanism is provided on the side of the seat body 1, and the anti-collision mechanism includes a fixing bolt 3, which is fixedly connected to the surface of the seat body 1, and a protective side plate 31 is perforated on the surface of the fixing bolt 3, and a limiting sleeve 32 is fixedly connected to the surface of the protective side plate 31, and a second spring 33 is sleeved on the surface of the limiting sleeve 32, and the end of the second spring 33 away from the limiting sleeve 32 is in contact with the surface of the seat body 1, and a nut 34 is threadedly connected on the surface of the fixing bolt 3. The anti-collision mechanism is provided on the side of the seat body 1, which can effectively protect the side area of ​​the child on the seat body 1, thereby improving the safety of the child safety seat.

[0026] Furthermore, two groups of telescopic dampers 22 and first springs 24 are provided, and the seat body 1 is buffered on the base 2 by the telescopic dampers 22 and the first springs 24. During the sliding process of the seat body 1 on the base 2, it is subjected to the buffering force of the telescopic dampers 22 and the first springs 24, thereby ensuring the stability of the seat body 1 on the base 2 and ensuring the safety and comfort of the children on the seat body 1.

[0027] Furthermore, a guide groove is provided on the surface of the base 2, and the guide rail 21 slides on the guide groove of the base 2. The guide groove of the base 2 is arc-shaped, and the guide rail 21 is also arc-shaped. The seat body 1 slides in an arc on the base 2 through the guide rail 21, and the second movable block 25 slides on the base 2 following the seat body 1, and the elastic force of the first spring 24 acts on the seat body 1 through the second movable block 25.

[0028] Furthermore, the side of the buffer pad 26 close to the base 2 is arc-shaped, and the buffer pad 26 is connected to one side of the base 2 through sliding contact with the seat body 1. When the impact force is large, the buffer pad 26 cooperates with the telescopic damper 22 and the first spring 24 to buffer the seat body 1, thereby improving the safety performance of the buffer mechanism.

[0029] Furthermore, two groups of protective side panels 31 are provided and are located on both sides of the seat body 1. Circular holes are opened on the surface of the protective side panels 31, and the fixing bolts 3 are connected to the circular holes of the protective side panels 31 through the holes. The second spring 33 is in contact with the surface of the protective side panels 31, and the limiting sleeve 32 limits the position of the second spring 33 on the surface of the protective side panels 31, thereby limiting the position of the second spring 33 away from the side of the protective side panels 31 in contact with the seat body 1, so that the second spring 33 can effectively output the elastic force to the protective side panels 31.

[0030] Furthermore, the elastic force of the second spring 33 acts on the protective side panel 31, and the protective side panel 31 is in contact with the surface of the nut 34 under the elastic force of the second spring 33. At this time, the protective side panel 31 is restricted on the surface of the fixing bolt 3, and the seat body 1 supports the protective side panel 31 through the fixing bolt 3. When the protective side panel 31 is hit, the second spring 33 can cushion the impact, thereby improving the protective ability of the protective side panel 31.

[0031] Working principle: When the car stops suddenly or collides, the seat body 1 slides backward on the base 2 through the guide rail 21. At this time, the telescopic damper 22 rotates itself, the telescopic rod of the telescopic damper 22 is extended and retracted, the first movable block 23 and the second movable block 25 rotate at an angle, and the first spring 24 is pulled to deform, so that the telescopic damper 22 and the first spring 24 cushion the seat body 1 on the base 2. When the impact force is large, the buffer pad 26 further cushions the seat body 1 by contacting the base 2, thereby ensuring the performance of the buffer mechanism. Through the setting of the buffer mechanism, the impact force of the seat body 1 on the child is effectively reduced, and the safety and comfort of the child safety seat are improved.

[0032] The second spring 33 is limited on the surface of the protective side panel 31 by the limiting sleeve 32, and then connected to the fixing bolt 3 through the circular hole of the protective side panel 31. The protective side panel 31 is slid on the fixing bolt 3 so that the second spring 33 is in contact with and connected to the surface of the seat body 1. The nut 34 is threadedly connected to the fixing bolt 3 so that the nut 34 is in contact with and connected to the surface of the protective side panel 31. At this time, the protective side panel 31 can protect the side of the seat body 1. When the protective side panel 31 is hit, it can also be buffered by the elastic force of the second spring 33, thereby improving the safety of the child safety seat. In addition, the protective side panel 31 can be quickly replaced when damaged, thereby extending the service life of the protective mechanism.
